DEMOUNTABLE-RIM DISK WHEEL.

Application filed August 1, 18m. ticrzlal its. t9fild0.

My invention relates to that class of wheels Where a demountahle rim for pneumatic tires is made detachable from the Web of the Wheel and the object of the invention is to produce a desirable term of demountahle rim and a fastening therefor, on a disk wheel or other type of Wheel adapted to receive this type of rim, and the invention is set forth in the claim. Reference will he had to the accompanyin drawings, in which Figure 1 is a iront elevation of a portion of a Wheel. a

Figure 2 is a side sectional elevation of a portion of a Wheel.

Figure 3 is a transverse section on line 3-3 oi Figure l. I

Figure i is a section on line H of Figare It.

In the dravvin 1 indicates the huh oi an ordinary automohile Wheel.

2 indicates the brake drum.

3 indicates a disk forming the web of a Wheel.

i indicates a flange turned on the margin of the disk, and this forms the hearing tread on the Web of the Wheel.

5 indicates, a rim tor pneumatic tires, of What is-known as the Q. D. or quick detachahie type, having a side ring 6;

The Wheel disk has a lateral, peripheral,

integral flange d, and the main cylindrical hody 5 of the rim is rolled With an internal head 7, near its outer side, fitting the disk flange, which is marginally hent toward the rim and in lateral contact with the head. Glam ing clips 8 are removahly secured to the dish by bolts 10 and fixed nuts ii having lateral lags i2 fined to the dish by rivets it.

The inner ends of the clips have rejections Which bear on the disk and their opposite ends have projecting portions which press, at 9, a ainst the lateral face of the rib or head when the bolts are screwedhome.

At intervals Where the clips 8 are secured to the disk, the disk is embossed or set inward for a short distance as is indicated by the inset portion 14, the purpose being to give clearance for the head of the screws to come underneath the gutter of the rim.

The marginal flange a of the disk is Wider between the clamping clips than the sections 14 Where the same is embossed and this wider tread is shown by section in Figure 4.

By providing the rim with the head 7,

-Whichiorrns a snug fit over the margin of the disk, I am able to make the lightest rim structure consistent with the other desirable features of a demountable rim disk Wheel.

The air stem tor a pneumatic tire is shown as an angle valve stem indicated by 16., and the dish is notched out at 17 to permit the entry of this valve stem. What it claim is 1 i in a device of the class described, a disk forming the web of the Wheel and having a marginal tread flange turned thereon, a dem'ountable rim having an internal head til) adapted to seat on the tread flange of the said disk and said tread flange being narrower at certain intervals than at the main front telloe face portion of the disk.
